1 '0 all whom it may concern:

Be it known that I, WVILLIAM E. KEMP, a citizen of the United States, and a resident of the city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Recording Instruments for Vehicles, of which the following is a specification.

The present invention relates to recording instruments for vehicles.

In these times of efficiency engineering, it has been found desirable to produce permanent records of vehicle'performance's. As long as the record relates to passenger carrying vehicles, for instance automobiles, a simple speed recording instrument is suiticient, the latter recording not only the speed of the travel and the distances traveled, but also the time consumed in stoppages, indicating clearly the working time of the'driver of the vehicle, the number of miles the vehicle has traveled, and the rate of speed at which the vehicle has been driven. As soon as, however, the performance record of a truck, for instance of a motor truck, has to be taken, another element enters into consideration, to wit: the load carried by the vehicle, and naturally the time consumed in loading and unloading.

The use of speed recording instruments on motor vehicles is old and well known. Such instruments comprise usually a clock work driven record tape carrier, in combination with a marker that is actuated by one of the wheels of the vehicle, thereby producing in the weliknown manner a record of the speed, distance and stoppages of the vehicle. It has also been proposed heretofore to provide trucks, such as motor trucks, with a. weighing mechanism and mileage recorder, such instrument including arccord sheet, in combination with a marking device that is actuated bythe depression of the vehicle body under the weight of the load, combined with a mechanism that is operated by one of the carrying wheels of the vehicle for moving said sheet to indicate thereon the distance the Vehicle has traveled. If both of these devices were mounted on the same vehicle, two independent records would be obtained, one record tape being actuated by a clock mechanism and the other tape by one of the vehicle wheels. These two records could, therefore, not be read conjointly, there being no relation therebetween.

It is now one of the objects of the present invention to bring the speed, distance and stoppage record of a vehicle in such relation to its load record that they can be read together, thereby securing a record indicating the following data:

1. The time at which the vehicle is started in motion, and the periods of time during which it is in motion.

2. The point or points of time at which the moving vehicle comes to astop, and the time during which the stop continues.

3. The speed of travel, and also the changes of speed.

4. The distance traveled by the vehicle.

5. The weight of the load carried by the vehicle in relation to time and distance, and

6. The time consumed in loading, unloading, or partially unloading the vehicle.

With these and other objects in view, which will more fully appear as the nature of the invention is better understood, the sameconsists in the combination, arrange ment and construction of parts hereinafter fully described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claims without departing from the spirit or'sacrificing any of the advantages of the invention.

Two of the many possible embodiments of the invention are illustrated in the accompanying drawings, in which Figure 1 is a longitudinal vertical section taken through a portion of a motor truck with the recording instrument, forming the subject matter of the present application for Letters Patent, mounted thereon; Fig. 2 is a plan view of a portion thereof; F ig. 3 is a front elevation of the recording instrument; Fig. 4. is a section taken on line 4.-4 of Fig. 3; Fig. 5 is a section taken on line 5-5 of Fig. 3; Fig. 6 is a section taken on line 66 of Fig. 3-; Fig. 7 is a section taken through a detail of one of the marking devices of the instrument; Fig. 8 is a section taken on line 8-8 of Fig. 7; Fig. 9 is a section taken through the record tape carrier; Fig. 10 is a section taken on line cover removed, in order to more clearly show the drum is'formed a spur ear 48, meshf tion of a vehicle wheel and the mechanism 10-10 0f Fig. 9; Fig. 11 is a section taken ,record tape carrying device, the latter comthrough the .tensioning device of the record prising a drum 42, which cooperates with ating device of the. arm carrying the other thereon.- v

The drum 42 and two reels are disposed horizontally, and at a suitable distance above the said drum are located two slotted guides 62, extending in parallel relation to the longitudinal axis of said drum, and being attached in any suitable manner to the base plate of the casing 36. Into the slot of each guide extends a sliding head 63, one carrying a stylus 64 hereinafter referred to as the speed recording stylus and the other one having attached thereto a stylus 65 hereinafter termed the load recording stylus. Both styli are moved back and forth parallel to the longitudinal axis of the drum, their pencils or other marking devices being forced against the drum by springs 66. To

the pencil holding tubes 67 of the styli are attached sh'ort links 68, which are fulcrumed at 69 to arms 70. Each ofthese arms is provided with two rounded projections 71. The rounded projections of the arm of the speed recording stylus engage diametrically opposite portions of a face cam 73, which is 1'0- tatably mounted upon a stud 74, the latter being carried by a lever 7 5, that is fulcrumed at 76 to the base plate of the casing 36, a set screw 77 engaging a slot 78 in said lever and serving to fix the position of the latter upon the said base plate. The arm of the speed recording stylus is pivoted at 79 to a stem 80, having a reduced end 81 fitting into a bore 82 in the stud 74. The rounded projections of thearm 70 are held in contact with the cam 73 by a spring 83, that is attached to the lever and bears against the stem 80. The cam 73 is actuated from one of the front wheels 84 of the truck. To this wheel is attached for this purpose a disk 85, having a cam 86, with which engages a lug 87, carrying an anti-friction roller 88. The lug 87 is formed upon a plunger 89, reciprocably disposed in a guide 90, the latter being preferably attached to the steering arm of the m0- tor truck. The cam 86 is shaped in such a manner that the plunger will be moved back and forth, completing one cycle during each revolution of the vehicle wheel. A spring 91, bearing against the guide 90 and an enlarged portion of the plunger 89, causes the anti-friction roller 88 to contact continuously with the cam 86. The movement of the plunger 89 may be transmitted to the cam 73 in the following manner: The last named cam is provided with a worm gear 92, in mesh with a worm 93, which is suitably journaled in the casing 36 and has fixedly attached thereto an escapement wheel 94. actuated by a detent 95, that is pivoted at 96 to a As. the

lug 97, the latter being formed upon the easing 36. The detent is fulcrumed at 98 to a plunger 99, projecting through a tubular extension 100 of the casing, said extension serving to guide the reciprocating motion of said plunger. The plungers 89 and 99 are joined by a flexible connection, for instance by the tension member 101 of a Bowden type of flexible connecting means, the compression member 102 of the said connecting means being attached to the guide 90 and to an externally screw threaded sleeve 103. The extension 100 of the casing 36 is also externally screw threaded. The threads of the extension 100 and of the sleeve 103 run in opposite directions, and are engaged by a turn buckle 104: to permit of an adjustment 7 of the length of the compression member 102 of the flexible connection. A spring 105 bears against the casing 36 and a collar 106 upon the plunger 99, carrying the last named plunger toward the cam 73 when the cable 101 is permitted to-move toward the recording instrument.

As mentioned above, transversely the record tape 30 indicates two miles of travel of the vehicle, or in other words a movement of the speed recording stylus across the tape represents a distance of two miles. Inasmuch as the circumference of the vehicle wheel is known, it is very easy to calculate the ratio between the worm 93 and the worm gear 92- to cause the latter to make one-half of a revolution for two miles travel of the vehicle. The distance between the stud 71 and the longitudinal axis of the worm 93 is adjustable, the said stud being mounted upon the lever 7 5, thus permitting the cam 73 and the worm gear attached thereto to be replaced by a smaller or larger one, as the size of the vehicle wheels may require.

The arm 70 of the load recording stylus is also provided, as above mentioned, with two rounded projections 71, engaging dia metrically opposite portions of a face cam 107. This cam has a spindle 108 rotatably mounted in the base plate of the casing 36, the arm 70 being pivoted at 109 to a stem 110, the reduced end 111 of which fits into a bore 112 in the spindle 108. The rounded projections of this arm are held in contact with the cam 107 by a spring 113, that is attached to the base plate of the casing 36 and bears against the stem 110. Upon the.

cam is formed a spur gear 114, in mesh with a rack 115, that is secured to .a sliding plunger 116, the latter projecting through a tubular extension 117 of the casing 36. A spring 118 is wound upon the plunger 116, and bears against the casing and against a collar 119 upon the plunger 116, its purpose being to force the rack 115 upward. The plunger 116 is connected with the vehicle springs by a. mechanism which transmits the variations of the depressions of the springs. The blade springs 120 must be strong and to the said plunger, or in other words transstifl enough to move the flexible cable 123 mits the variations in the load on the i ehicle. and the elements connected therewith with- This transmitting mechanism comprises two out becoming deflected. Inasmuch as there blade springs 120, one of which is attached is always atension on the-cable, the deflecto the forward axle of the vehicle by the 'tion of the springs will remain substantially usual spring clip 121, and the other one to constant. The cable 123 connects, as is ohthe rear axle by the usual spring clip 122; vious from the foregoing, .the two axles of These blade springs extend'to the lnngirudithe vehicle and'will thus produce in-the load nal middle line of the vehicle, and have atrecording stylus actuatmg mechanism a tached to their free ends a flexible cable movement which is the average of the move- 123, running over sheaves 124, thatarecarried ments of thetwo ends of the vehicle body, by lugs. 125 upon the bottom of the motor so that an unequal loading of the vehicle at truck.

The lever 128 is provided with stylus. As soon as, however, the vehicle is .an arc-shaped slot 132, and in this slot are started in motion, the cam86 actuates the disposed clamping means 133 ofalink-134, plunger 89- and thus the plunger 99.

the swinging lever 128 in the direction of the arrow shown in Fig. of the drawings, and causing a corresponding movement of the link 13%, and thus of the plunger 116. This movement is transmitted to the cam 10? by the rack 115 and the gear 111 cooperating therewith, causing a partial rotation of the am, which moves the load recording stylus a corresponding distance transversely of the record tape. Obviously, if load is taken ,oli' the vehicle, the load recording stylus will move in the opposite direction. In this manner a load diagram 143 is obtained on the record tape, as shown in Fig. of the drawings, from which it appears that at 6.30 the loading was started and continued until 7 .30, the load placed on the vehicle being 140%. From this point until 10.30 the load was constant, and from 10.30 until 11.00. some of the load was removed, bringing it down to 110%, and from there it was constant, etc. In connection with this diagram, it is to be noted that 100% means the normal capacity of the truck, for'instance five tons, andv in this,

manner 160% would mean eight tons, and so on. I

In the devices illustrated-in Figs. 1 to 20, inclusive, the two recording styli are placed as close together as the structure will permit; (in the case illustrated herein the distance between the two being somewhat exaggerated, the normal distance being about 'lVhen therefore the two diagrams are to be read conjointly, corresponding corrections will have to be made. If, however, the tape shown in Fig. 21 of the drawings is employed, wherein the load diagram and the speed diagram are drawn side by side, the two styli could be placed in a line parallel to the axis of the drum 42, and in this case obviously no correction is needed.

The diagram 14). gives, as appears from above, a distance, speed and stoppage record, when read in conjunction with the time graduations; The load record diagram, when read in connection with the time graduations, not only gives a record of the load on the vehicle, but also the time consumed in loading and unloading. Inasmuch as both diagrams are reduced toa common scale, to. Wit: time, they are readableconjointly, that .is to say with reference to Fig. :20, it will appear that, while the vehicle was at rest from 6.30 lo 7.30, load was put on, the load remaining constantuntil 10.30. Examining, however, the speed diagram, we find that from 8.15 to 8.45 the vehicle was stationary and the load constant, indicating thereby some irregularity on the part of the driver. Moreover, not only can the tonhours and mile-hours be ascertained, but also the ton-miles, by reason of the above referred to common scale. This common scale, that is the time, thus forms the connecting link between, the mile-hours and ton-hours, enabling the record to be reduced toton-miles, that is to say to the desired standard of comparison of vehicle performance.

it is to be observed that, while herein a detailed description of the actuating mechanisms of the styli has been given, others may just as well be employed without departing from the invention, which lies mainly, as indicated above, in the provision of a record tape carrier that is operated by a clock mechanism and cooperates with two markers, one of which is actuated by one of the wheels of the vehicle, and the other one by the depression of the vehicle body under the weight of the load thereon. The invention lies also'in the method of producing two independent diagrams f d reducing the same to a common scale so as to be readable eitherseparately or conjointly, for the purpose set forth.
